I have konfabulator for OSX which is a nice little app that puts useful widgets on your desktop. Like the weather. Which is great this time of year because you never know what it will be like outside.

I checked it tonight, and cannot figure out what the graphic is for Sunday. Apparently we will have an average of 70 degrees, with a chance for exploding broccoli shrapnel. I am not sure how you prepare for that, so you better start thinking.
